She noted that much of their journey has been shaped by crossed signals, mismatched timelines, missed opportunities, and constant longing. She further added,"What actually happens when you get together? Maybe they hate each other. Maybe like, oh, he's so annoying. You again."Atwell further emphasized that their chapter remains a lasting love story and fans continue to enjoy watching them. She admitted that she felt humbled by the audience’s response and realled asking herself,"Is it a nomad, is he? What happens after the dance?"Those questions led to long discussions, which eventually shaped a new structure for the story. In Avengers: Doomsday, Peggy is shown as the adult in the relationship, the dependable one. However, Atwell pointed out that when an actor plays the straight character who is always longing, the role can sometimes feel slightly dry.Follow Soap Central for more updates on Avengers: Doomsday.
